871628 divided by 42 
Let's see how many times 42 fits into 871628.

Moving on to step 1:
The number 42 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 42

Advancing to step 2:
42 goes into 87 2 times with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 84 from 87, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 42

Going ahead to step 3:
When dividing 31 by 42, we get 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 20.0
Subtracting 0 from 31 leaves us with 31.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 42

Going ahead to step 4:
316 divided by 42 is 7 with a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 207.0
Deduct 294 from 316 and we're left with 22.
Bring next digit (2) of the dividend behind the 22 and repeat the process: 222 / 42

On to step 5:
42 can be fit into 222 5 times, resulting in a remainder of 12.
Record the quotient 5 as the next digit in the result. 
Result so far: 2075.0
Subtracting 210 from 222 leaves us with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 42

Going ahead to step 6:
42 can be fit into 128 3 times, resulting in a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 20753.0
The remainder is 2 after subtracting 126 from 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
42 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 20753.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
42 can be fit into 200 4 times, resulting in a remainder of 32.
The next digit of our result is 4. 
Result so far: 20753.04
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
The number 42 fits into 320 7 times, leaving a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 20753.047
If we take 294 away from 320, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
When dividing 260 by 42, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 20753.0476
If we subtract 252 from 260, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
42 can be fit into 80 1 times, resulting in a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 20753.04761
If we take 42 away from 80, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 12:
If we divide 380 by 42, we get 9 and a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 20753.047619
If we take 378 away from 380, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
20 divided by 42 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 20753.047619
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
42 goes into 200 4 times with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 20753.04761904
If we take 168 away from 200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 20753.04761904 with a remaining 3.2e-08.
